Abstract
An enhanced mobile communication device, or on-board equipment, communicates according an enhanced ad-hoc mode of communication and an infrastructure mode of communication. A method switches between the enhanced ad-hoc mode of communications and the infrastructure mode of communications. The enhanced mobile communication device receives content and updates a geographic database. The enhanced mobile communication device reads the geographic database and transmits content. Data, such as location information from global positioning satellite signals, is collected by the enhanced mobile communication. On-board software of the enhanced mobile communication device communicates with the geographic database for computing routes, paths, and turn-by-turn direction.
